Vibration Damper,Armour Rod
The company offers a 4D series of anti-vibration hammer tuning fork design for Stockbridge, multi-resonance sound damping devices, mainly used for weakening and fragmentation of fiber optic cable due to aerolian vibration generated by the impact energy.

Configuration:
It is commonly used in the anti vibration device of OPGW cable and ADSS cable.
Configuration of installation quantity of OPGW damper
Cable Dia.(mm)		Span(m)
d<12		100~300			300~600			600~900
12≤d<22		100~350			350~700			700~1000			1000~1200
Quantity of damper (each span)		2			4			6			8

Configuration of installation quantity of ADSS damper
Cable Dia.(mm)		Span(m)
d<12		100~250			250~450			450~700
12≤d<22		100~250			250~500			500~800			800~1000
Quantity of damper (each span)		1			2			4			6

Note: on the critical span, for the sake of safety, the number of vibration dampers should be more or less.
